Orange Yane no Chiisana Ie is written by somebody who has presumably never actually talked to a person in real life. Every character is a parody of a parody of a caricature of a caricature of a person, with the most comically tropey and idiotic reactions to any given situation.
Ninomiya is a stereotypical hard-working, well meaning but clueless dad, which isn't a crime on its own, but when you introduce Natsumi, the dynamic becomes unbearable. Natsumi is the most frustratingly braindead character imaginable. She takes the slightest problem and blows it entirely out of proportion, choosing to take misunderstandings and run with them instead of behaving like an actual adult and talking about anything. Her histrionic stupidity speaks to an awfully skewed perception of women by the mangaka. It's not as though stupid misunderstandings caused by miscommunications are uncommon plot devices in anime and manga, but Orange Yane's usage of them crosses the line from acceptable into sickening. Every conflict feels so forced and meaningless when you realize that any two people acting like grown adults and talking to each other would resolve it quickly and easily.
Orange Yane no Chiisana Ie is like a clown car packed full of the worst narrative devices you can imagine. It is a trash fire. Do not read it.
